SPECIFICATION forming pari; of Letters Patent No. 262,894, dated August 15, 1882. Application led May 19, 1852. (No model.)

To all whom 'it may concern:

Be it known that I, GEORGE H. HELVEY, of Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Traction-Engines, of which the following is" a specification.

This invention pertains to traction-engines arranged to transmit power to a machine-as a thrasher-While standing, and relates to the transmitting devices between the crank-shaft. of the engine and the traction-wheels.

In the accompanying drawings, Figure l is a plan of the engine with some details in section, and Fig. 2 is an end View ot' the hub of the fly-Wheel,

The letters denote: A, boiler; B, tractionwheels; C, crank-shaft of engine, the engine itself not being shown; D, a pinion on the crank-shaft; E, a iiange or shroud on this'pinion; F, holes in the face ot' this flange; G, the iiy-wheel; H, the hub ot' the y-Wheel; I, a pin arranged to slip in a hole bored in the iiywheel hub parallel with the crankshaft; J, a set-screw in the hub, bearing on the pin I to hold it where set; K, train of idle-gears hetween crank-shaft C and traction-wheels B, and L the gears attached to the traction-wheels.

The pinion D is loose upon the crank-shaft, and when the pin I is in the position indicated in Fig. l the train K and traction-wheels B remain motionless while the crank-shaft is trailsmitting power through a belt on the ily-wheel to some machine. The belt being moved and the pin I pushed inward till it engages with a hole, F, in the flange of the pinion D, the pinion will be locked to the crank-shaft and motion transmit-ted through the train K to the traction -wheels. 1t' it is desired to pump up water While the engine is temporarily stopped on the road, the pin I is withdrawn and the engine set running without affecting the tractionwheels.

I claim as my invention- In a road-engine, the combination, substantially as set forth, of a crank shaft arranged and adapted to be revolved bya steam-motor, a pair of bearings to support said shaft, a band- Wheel fixed to ,said shaft and adapted to transmit motion from said shaft by a belt, a gearpinion disposed between said band-wheel and one of said bearings on said shaft, and adapted for transmitting motion from said shaft by gearing, a shroud or iiange upon said pinion, and

a clutchpin iitted to slide through a hole in the hub ot' said band wheel and engage in a hole in the shroud of said pinion, whereby said transmissions may be effected together or independently.
